Answer

To solve the question of identifying the incorrect match, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the first option: Male external genitalia is the penis.**
- The penis is indeed the male external genitalia responsible for the delivery of sperm during reproduction. This statement is correct.

2. **Identify the second option: Male accessory gland is the seminal vesicle and prostate.**
- The seminal vesicle and prostate are both male accessory glands, along with the bulbo-urethral (Cowper's) gland. These glands produce secretions that nourish and transport sperm. Therefore, this statement is also correct.

3. **Identify the third option: Lubrication occurs from the bulbo-urethral gland.**
- The bulbo-urethral gland does produce a secretion that lubricates the penis during intercourse. This statement is correct as well.

4. **Identify the fourth option: Scrotum situated inside the testis.**
- This statement is incorrect. The scrotum is an external pouch that houses the testes, which are located inside the scrotum. The scrotum is situated outside the abdominal cavity to maintain a lower temperature necessary for sperm production. Therefore, this is the incorrect match.

### Conclusion:
The incorrect match is: **Scrotum situated inside the testis.**
